This is an above-average episode in an above-average anthology series. I'm not sure why it is ranked on IMDb lower than certain other episodes, but it maintains a sense of mystery and suspense, and the cast is very good. It's especially nice to see William Windom in another supernatural tale (his having been in one of the very best Twilight Zone episodes, not to mention one of the very best Star Treks), and Carolyn Jones, who is in practically every shot, is also solid. Avoid watching Sebastian Cabot's introduction of this episode, as it gives far too much away.
